(6)多执行机构选用节省调速时防止只选用一个液压泵供油体系中有多个执行机构时，各个机构不能始终保持对流量、压力需求的协调一致。而选用节省调速回路却不可防止地存在溢流丢失和节省丢失。此刻，若只选用一个泵供油，一定以体系所需***高压力和流量为泵的挑选根据，不能***适应低压小流量和高压大流量的状况，致使体系的功率很低。(7)当由于液压体系的需要而选用增压油箱时，其压力P≤0.16-0.2MPa。9510390070AZ-P-N-12-028-LQC12MA9510390071AZ-P-N-12-032-LQC12MA9510390072AZ-P-N-12-036-LQC12MA9510390073AZ-P-N-12-020-RQR12MB9510390074AZ-P-N-12-022-RQR12MB9510390075AZ-P-N-12-025-RQR12MB9510390076AZ-P-N-12-028-RQR12MB9510390077AZ-P-N-12-032-RQR12MB9510390078AZ-P-N-12-036-RQR12MB9510390079AZ-P-N-12-020-LQR12MB9510390080AZ-P-N-12-022-LQR12MB9510390081AZ-P-N-12-025-LQR12MB9510390082AZ-P-N-12-028-LQR12MB9510390083AZ-P-N-12-032-LQR12MB9510390084AZ-P-N-12-036-LQR12MB9510390085AZ-P-NFF-11-020/019/019-RDC12MB-S00149510390086AZ-P-N-12-020-RPR12MA9510390087AZ-P-N-12-022-RPR12MA9510390088AZ-P-N-12-025-RPR12MA9510390089AZ-P-N-12-028-RPR12MA9510390090AZ-P-N-12-032-RPR12MA9510390091AZ-P-N-12-036-RPR12MA9510390092AZ-P-N-12-020-LPR12MA9510390093AZ-P-N-12-022-LPR12MA9510390094AZ-P-N-12-025-LPR12MA)
